Bottom bracket tapping tool Cyclus Tools BSA 1,370"x24TPI (720008)

The Cyclus Tools threader is designed for BSA bottom bracket shell threads (1,370" x 24 tpi). It can produce a concentric thread.

• Tool-holder sleeve inner diameter: 16 mm.
• Insert both sides of the threading tool simultaneously to prevent it from tilting and damaging the existing thread.

Note: Letters and markings on the tool refer to the tool itself, not to the left or right side of the bicycle. The “R” marking is for chasing a conventional right-hand thread; turn the tool to the right, clockwise. The “L” marking is for the left-hand thread of the bottom bracket shell; turn the tool to the left, counterclockwise.

Use cutting oil suitable for the material being machined.
